I have an idea to wire a light strip along the bottom edge of the rear window (top edge when the window is swung up so the light shines into the rear of the Jeep). I could do this with a manual switch, but would like if the light would just automatically turn on whenever the tailgate is opened. I noticed there is a message on the dashboard if the tailgate is not closed fully, which means there must be a wire sending that message from the tailgate. Does anyone have any idea which wire this would be and could I hypothetically splice into it to give power to the light anytime the tailgate opens up?
